Abstract

A sheet or tractor media handling system for a compact printer having a housing, a cut-sheet supply station and a rotatable print platen constructed and located to feed top sheets from said supply station through a print path ingress past a print zone and out a print path egress. The system includes a mode control assembly for selectively controlling the movement of said supply station for sheet or tractor media; a pair of guide wheels constructed and mounted for engagement with tractor media along a tractor media inlet passage; bail rollers engaging the platen between the print path ingress and egress; and a variable spring system for urging the bail rollers against the print platen with higher or lower nip pressures for sheet or tractor media conditions.
